An event will only be triggered when both the signature and topic 0 match. By default, `topic0` is equal to the hash of the event signature.
+## Transaction Receipts in Event Handlers
+
+Starting from `specVersion` `0.0.5` and `apiVersion` `0.0.7`, event handlers can have access to the receipt for the transaction which emitted them.
+
+To do so, event handlers must be declared in the subgraph manifest with the new `receipt: true` key, which is optional and defaults to false.
+
+```yaml
+eventHandlers:
+ - event: NewGravatar(uint256,address,string,string)
+ handler: handleNewGravatar
+ receipt: true
+```
+
+Inside the handler function, the receipt can be accessed in the `Event.receipt` field. When the `receipt` key is set to `false` or omitted in the manifest, a `null` value will be returned instead.
+

## Experimental features
Starting from `specVersion` `0.0.4`, subgraph features must be explicitly declared in the `features` section at the top level of the manifest file, using their `camelCase` name, as listed in the table below:
